I've had my ayi for the entire time I've been here - when I moved universities she came with me. I pay her 50Y per session - which lasts as long as it takes - sometmes 2 hours, sometimes 4-5. After a party I also have her come to clean because I can't face it. For that horror I give her 100Y. She comes once a week, brings me food every now and then, we sit and chat about life, the universe and everything, she helps me with my Chinese (she doesn't speak English). My Chinese mate laughs because he says she has modified her Chinese to my level so we understand each other perfectly!!
She does my washing, washing up, vacuuming, dusting, floor washing, window cleaning, turtle cleaning etc. Whatever I haven't done she will take on.
At the previous uni she lived close to where I was and I paid her 25, but here my apartment is twice the size and she has to catch 2 buses to get to me, so I figured if travel time for teachers was fair, travel time for cleaners is too! She also works for several of the other teachers, and I have introduced her to the other FTs here and a couple of friends.
She's totally trustworthy, I have given her a spare set of keys and she comes even when I am on holidays.
It is SOOO nice to come into a clean apartment. And it's nice to have a friend.
